PROBLEM TO BE SOLVED: To provide a vehicle body upper part structure in which both ends of a roof panel do not impair design, a roof molding fitted to a groove is abolished, and pulse laser welding is adopted.SOLUTION: In the vehicle body upper part structure, an inner laminated bonding part 75 in which ends (inner upper layer flange 81, inner intermediate flange and inner lower layer flange 141 of an inner rail 71) of a plurality of rails (inner rail 71, reinforcement rail 72 and outer rail 73) are superposed on a roof rail 13 is provided below the roof panel 12, a shelf joint part 76 is formed while continued the inner laminated bonding part 75, both ends (left end 57 and right end) of the roof panel 12 are joined to the shelf joint part 76 by an adhesive and a temporarily fixing welding part (laser welding part), and the temporarily fixing welding part is hidden by a dust sealer 65. The temporarily fixing welding part is formed between an edge 143 formed on the ends (left end 57 and right end) of the roof panel 12 and the adhesive 14. |
